Simon Cowell tried to joke his way out of reports that he will become a father, but he finally came clean.

The "X Factor" judge and reality TV/music executive walked the red carpet Tuesday night for the London premiere of the One Direction documentary "This Is Us"that Cowell co-produced. The Daily Mail reported Cowell joked about how proud he was of the boy band, who he signed to their record label.

A juicy unauthorized biography about “X Factor” head honcho Simon Cowell has hit the streets – and, according to its author, it packs more fact than fiction.

Tom Bower, the writer behind the allegedly true-life tale “Sweet Revenge,” told the U.K.'s ITV1 on Monday that he actually had the former “American Idol” host’s cooperation in writing the book up to a certain point, according to the Telegraph.

"I flew with him a lot to America on his private jet, I was on his yacht, visited him often in his house in LA," Bower said. "I got to know him very well and we got on very well. In the end I reported what I found."

Simon Cowell reportedly had a fright over the weekend after a woman allegedly broke into his London home.

According to reports, the reality show head honcho was just about to watch himself on "The Jonathan Ross Show" that Saturday night when he heard a strange noise coming from inside his Kensington-area mansion.

The Daily Mail reports that Cowell's rep said on a U.K. morning show Monday that when the entertainment mogul went to investigate, he found an unknown woman in his home with a brick in hand.

With the first season of "The X Factor" scheduled to wrap this week, Simon Cowell says he's keeping a level-headed perspective on how well the series has launched in the States.

"Never finish a season thinking it's the best you've ever done, because you have to feel that you can get better," Cowell, who serves as one of "X Factor's" judges/mentors, told CNN Monday. "I think I probably came here a bit too cocky, but I'm cocky by nature."

He recalls that he was coming off a "massive" run overseas, and with the adrenaline pumping, he couldn't wait to bring "X Factor" to America. "One of these artists is going to be the legacy of this year...and it's going to be better next year."
